deploy walkthrough, API validation, inference client, Hetzner provider

Browse source 
- Interactive deploy command with 8-step walkthrough:
  framework → provider → token → SSH → server → inference → tailscale → discord
- .env file generation from walkthrough config
- DeploymentConfig struct with framework-aware defaults
- Inference API client with validation for Venice, OpenRouter, OpenAI, Anthropic
- Hetzner Cloud provider: token validation, SSH key listing
- DotEnv parser/writer with schema validation
- Destroy command with confirmation prompt
- Validation subcommand for checking existing .env files
- All tests passing, go vet clean
